OIL AND WATER SEPARA'IOR AND'FILTER. t

, No. 866,454. i

To all whom it "may enact/"rt;

Be it known that we, tnA'RLEs FREIERMUTH and States, residing atBrooklyn, in the county of Kings and 1 State of New York, have inventedcertain new and useful Improvements in Oil-and Water Separators andFilters, and do hereby declare that the following isa full,

had to the annexed drawings, making a part oi this specification, and tothe letters and figures of reference marked thereon. v L

The present invention'has for its object to provide a simple andet'fective means for separating the oil and other impurities from steamcondensation whereby all the oil'and water usually passing into thesewer-are saved, thereby reducing the costin the use of coal and waterto a. minimum as well as dispensing with the necessity of boilercompounds and removing the danger of boiler explosions on account of adirty boiler, thus se-' curing the advantage of a filter and purifierthat will be perfect in its action, simple in construction, and effect-I ive in its purpose. I .The invention consists in an oil and waterseparator and filter constructed substantially as shown in the Figure 1of'the drawings is a sectional view partly in elevation of an oil andwater'separator and filter con' structed in accordance with ourinvention. Fig. 2 a top plan view thereof. ,Fig. -3 a detail sectionalview partly in elevation on an enlarged scale of the ball valve,-

being supported upon suitable legs a and is open at th top and providedwith a convex bottom 12. i

An upright central tube B is located within the tank A and is supportedat'its lowerend by braces csecured thereto and to theconvex bottom b,said tube being open at both endsnl t v A supplemental perforatedbottom-O is suitably secured to the outer side of the tube Bat its l0 erend, and its outer periphery; is-supported by the bilckets d secured'totheside wall' of thetank; i Above thesuppleniental perfdratcd bottom Gisa plu rality of perforated partitions]? located between the wall of thetan}; .A'and the exterior of the tube Bpa's shown in 'Fig. I of the?drawings. These partitions D are circular and in the-form oia diskhavinga central opening to pass over thojend of the central tube B anddescribed whereby afresh supply of filtering mediiirnmay be substitutedfor the old and the perforated parti- Specification of Letters 19' tent.Application filed May 15,1907.

The particular-location of the 1 Pa.tentedSept.17,1907.

At the bottom oft e tank A is a suitable drain-cock e and located withinthe tank below'the perforated supplemental bottom C is a ball-valve E ofany well known construction, said. valve having a vertical guideextension g for the stem h which extends up into the tube B.

The stem h at its lower end is connected to the ball 11 in thevalve-shell and-at its upper mid'i'salfiiie'd a suit able float F sothat the valve will be controlled by the vertical n10 vement'of thefloat through the action of the water in the tube. v

A suitable gage G connects with the tank A to indi-- cate the amount ofwater 'thcrcin and is also provided water; the overflow pipe and thedrain pipe communieating with the tank above the upper one of theperforated partitions D, as shown in Fig. l of the drawings.

The circular discharge pipe H is located within the" tank A andencircles the tube B and has perforations on its upper side for thedischarge of the water so that it will flow out evenly over the surface.

The discharge pipe H is connected to an inlet-pipe I by IIIGELIISOf agoose-neek orother form of coupling [so that the. two pipes maybB'dlSCODIlGCtQd when it is desired to remove the perforated partitionsD.

The water passing from the condenser or other source into the inlet-pipeI is discharged into the tank A through the perforations in thedischarge pipe H and thence passes down through the perforatedpartitions D and through the filtering mediinnf and through thesupplemental perforated bottom C and up into the central uprighttube Bas indicated by'thc arrows in Fig. 1

of the drawings.

To'relieve the filtered water, the ball-valve E is provided and operatedby a float F connecting therewith 'as hereinbeiore described, and whenthe water rises suiiiciently high in the tube Bto raise the float,- theball t upon the lower end of the stem h will be raised oli' its seat andthe valve opened to allow the filtered water to pass'through the pipe .lto a tank or pump.

.The central upright tube B is; located wholly within above. the bottomof the {tank so that a free irculation of 'the'filtered'watertrnay passfrom the tank into the tube from the lower end theredhtheraising oi thetube above the bottom of the tank forming a communication between thetwo which is essential to a successful operation of the filter.

ilfillho lower one ofthe perforated disks is stationary andit is firmlysecured to the tube and forms abrscc therefor to'retain said tube in acentral position with relation to the walloi the tank while theperforated disks aboveit are-removable. 1

central upright tu be thetank A and its lower end is suitably supportedioo with relation to the closed bottom of the tank so that acommunication will be formedbetween the two at the lower end of the'tube and entirely inc-losing the tube within the tank is considered anessential feature of the invention from the fact that the course offiltered water as it passes down through the filtering medium will takean upward course from the tank into the tube from the bottom thereof asit seeks its own levelenabling a perfect filtering action upon thewater.

The valve E may be of any suitable construction and may be locatedinside or outside the tank and operated by any means found best adaptedto the purpose.

' Having now fully described our invention, what we claim as. new anddesire to secure by Letters Patent, l SZ 1. An oll and water separatorand filter. comprising a tank having an overflow and oil drain, acentral upright tube supported above the bottom of the tank and inelosedwholly within the same whereby a communication is formed between thetank and the tube at: the lower end thereof. a stationary perforateddisk secured to the tube at the lower end to form a brare therefor, aplurality of removable disk and a filtering medium between the same. aremovable perforated discharge pipe eueircliu; the tube below the upperend thereof. and a valve operating means for allowing the passage of thefiltered water to a tank or pump, substantial]; as and for the purposeset forth.

2. An oil and water separator and tilreiz comprising a suitable tankhaving a water overllow and an oil drainpipe, :1 central upright: t'uhelocated in the tank, a perforated supplemental bottom secured to thetube, a plurality of removable perforated partitions located between thewall of the tank and the tube, filtering medium between the partitions.a removable perforateddischarge pipe eneireliue' the tube, and afloat-valve to control the dist'hal'gc of the tiltered water to a liankor pump, sub sianlially as and for the purpose described.
